RE: [WISPA] DC Inverter help
Can anyone give me a lead as to what I am looking for? I believe this http://tinyurl.com/lje7s is what I need, but I don't think I need 400Watts as all I will be pulling at several new tower sites are a few RB532's with their radios. I think I ought to keep the RB532s powered at 48VDC as they will be in excess of 200' up a tower. My intentions are to put a couple Marine batteries in an enclosure for back up power and have the DC inverter to keep them charged and have a seamless transfer if a power outage comes along. I have been putting these big honking APC UPSs in all my enclosures, but am trying to get something that will last longer in times of outages Any help would surely be a appreciated.

RE: [WISPA] DC Inverter help
Mac, Can you tap in to the battery lines on the UPS and add extra external batteries to extend the run time? This would give you the advantage of conditioned power and automatic switch over of the UPS, and you would still have any other management features of the UPS still available to you. Just an idea to consider.

That would work, but there are a couple problems with that particular one: 1. 3½ high by 17 wide by 12 deep (its too big) 2.

RE: [WISPA] DC Inverter help
Brian, I guess I am an idiot because I hadn't thought of that! I don't have any (hardly) of my APC UPS's overloaded and it would probably be pretty easy to do that. I bought some rack mount Compaq 3000Watt UPS's for the NOC and tied 4 Gel Cell 100lb batteries to each of those Compaq's. That has been working like a charm, but it scares the fire out of me to mess around them. While connecting them I managed to arc the wires and that produced a ball of fire that was bigger than I was! I later found out those 4 12VDC batteries in a series (48VDC) produces more than enough DC voltage to knock your guts out while it blows the bottom of your feet off.

Do a quick search on ebay for carrier access and you should be able to find it for less.

RE: [WISPA] DC Inverter help
Mac, Understood, volts is volts and need respect :-). Might think about doing it with some sort of switches or fuses on the external lines to allow you to change batteries safely and without having to take all of them off line at any one time. With fuses at the right rating they would pop if there were a short like you mention and maybe avoid problems, although that is just one more thing for a service call too.
